Characteristics and impact of faked interviews in surveys – An analysis of genuine fakes in the raw data of SOEP

Summary: Panel data offers a unique opportunity to identify data that interviewers clearly faked by comparing data waves. In the German Socio–Economic Panel (SOEP), only 0.5 percent of all records of raw data have been detected as faked. These fakes are used here to analyze the potential impact of fakes on survey results. Due to our central finding the faked records have no impact on the mean or the proportions. However, we show that there may be a serious bias in the estimation of correlations and regression coefficients. In all but one year (1998), the detected faked data have never been disseminated within the widely–used SOEP study. The fakes are removed prior to data release.* We are grateful to participants in the workshop on Item Nonresponse and Data Quality on Large Social Surveys for useful critique and comments, especially Rainer Schnell and our outstanding discussant Regina Riphahn.

Risk factors of severity of abuse against older women in the home setting: A multinational European study

ABSTRACT

This article examines the ecological risk factors of abuse against older women. Data from 2,880 older women were randomly collected in five European countries (Austria, Belgium, Finland, Lithuania, and Portugal) using a standardized questionnaire. Results indicate that overall 30.1 % older women had at least one experience of abuse in the past year. The findings demonstrate that a single emphasis on personal risk factors (e.g., health, coping) is important but too simple: Abuse is multifaceted and is embedded in environmental (e.g., loneliness, household income) as well as macrocultural contexts (e.g., old age dependency ratio).     

Tall claims? Sense and nonsense about the importance of height of US presidents

According to both the scientific literature and popular media, all one needs to win a US presidential election is to be taller than one's opponent. Yet, such claims are often based on an arbitrary selection of elections, and inadequate statistical analysis. Using data on all presidential elections, we show that height is indeed an important factor in the US presidential elections. Candidates that were taller than their opponents received more popular votes, although they were not significantly more likely to win the actual election. Taller presidents were also more likely to be reelected. In addition, presidents were, on average, much taller than men from the same birth cohort. The advantage of taller candidates is potentially explained by perceptions associated with height: taller presidents are rated by experts as ‘greater’, and having more leadership and communication skills. We conclude that height is an important characteristic in choosing and evaluating political leaders.     

Ethnic Composition and School Performance in the Secondary Education of Turkish Migrant Students in Seven Countries and 19 European Educational Systems

This article examines the effect of the ethnic composition on school performances in secondary education for Turkish students, using both cross‐national and Swiss national PISA 2009 data. At the school level our results show no effect of the proportion of natives or the proportion of coethnics and a negative association between ethnic diversity (we employ a residualized score of diversity on the proportion of migrants) and math performances. Consequently, we find no evidence for social capital advantages and an indication of barriers. Finally, we find no association between social capital variables on national or educational system level and math performance.     

The Liberalization of Maternity Leave Policy and the Return to Work after Childbirth in Germany

German federal law has increased the potential duration of maternity leave five times since 1985. A theoretical model demonstrates that the cumulative return probability at potential duration cannot decline unless the mother's employment conditions or career expectations change. We estimate return to work hazards from the German Socio-Economic Panel for women bearing children in the period 1984–1991 and predict cumulative return probabilities for first-time mothers and mothers with a previous birth. The pattern of cumulative return probabilities as potential duration increases is consistent with the hypothesis that employment conditions or career expectations frequently change for mothers taking longer leaves.     

Religiös-konfessionelle Kultur und individuelle Religiosität: Ein Vergleich zwischen West- und Ostdeutschland

In religious terms, East and West Germany are still two separate societies more than 20 years after reunification. While the large majority of the population in West Germany belongs to one of the two main Christian churches, the proportion of those without a denomination in East Germany is now more than 70 %. Moreover, as far as church involvement, confidence in the church and individual religiosity are concerned, the West Germans have a much stronger religious affiliation to the church than their East German counterparts. The main reason for this difference is the influence of different political systems and legal cultures in East and West during the period when the two parts of Germany were divided. The fact, though, that the process of secularization has continued unabated in East Germany since 1989, and that the religious and ecclesiastical discrepancies between the two parts of the country have, if anything, become stronger rather than weaker since then, would suggest that there are other factors at work here, too. In this contribution, we argue that one of the factors that needs to be considered is the dominant denominational culture that exists in each of the two parts of the country, a culture which is highly persistent, can easily reproduce itself, puts pressure on the respective minority cultures, and is able to diffuse into them. While the dominant denominational culture in West Germany is able to slow down the current processes of secularization, the secular, non-denominational majority culture in the East tends rather to produce effects which accelerate these processes. In this essay, we use a variety of empirical indicators (effectiveness of religious socialization, denominational affiliation, churchly affiliation, faith in God) to demonstrate these effects.
